Pee Power takes centre stage at Glastonbury

The Pee Power urinal that turns pee into electricity - designed by researchers at the University of the West of England (UWE Bristol) - is taking centre stage in the Stone Circle at Glastonbury Festival for the second year running.

The team of researchers from UWE Bristol, and workers from Oxfam and Dunster House shelter manufacturers, are using the festival like a field trial in advance of planned trials in Africa and India later this year.

The specially adapted urinal first appeared at Glastonbury last year, following its launch at the UWE Bristol student union in March 2015, but this time the team has created a unit twice as big and capable of accommodating up to 25 people at once.

The toilet will contribute to the facilities needed on site but the real purpose behind taking the unit to Glastonbury is to excite and inform the audience about a technology in its relative infancy that has the potential to change the lives of those living in countries where sanitation and electricity are off grid.

The unit is powered by urine fed through microbial fuel cells (MFCs) that generate enough electricity to light up the inside of the urinal.

Professor Ioannis Ieropoulos, Director of the Bristol BioEnergy Centre, Bristol Robotics Laboratory, at UWE Bristol, said, “The festival presents us with the opportunity to trial the technology, along the lines of its robustness and cleaning capability, in terms of the sheer numbers of people and therefore the amount of urine.

“The urinal at the festival this year is going to be built to the size we plan to use for refugee camps. We have also developed the microbial fuel cell unit so that it is much smaller and yet delivering the pee power with more power.

“Our ethos of reusing free resources – in this case urine, generating energy for free and also cleaning the urine so that it is suitable for agricultural use resonates with the Glastonbury Festival organisers who have made us feel very welcome. The benefits of a stand-alone system like the version we have designed is that it provides lighting that can be used in any environment and in any conditions with electricity being generated continuously from the waste without having to rely on the grid or other fossil fuel based technology.”

Andy Bastable, Water Sanitation Manager for Oxfam, said, “In most refugee camps around the world, and in poor slum areas, light is needed at night. The microbial fuel cells light up patches in the camp and this is important in regard to women's safety at night. Another bonus of this technology is the ability to charge mobile phones. There is potential for us to develop charging centres that would be particularly beneficial in refugee camps where families get split up.

“The project is in quite early days in terms of the field trials and Oxfam is hoping to work with the Bristol BioEnergy Centre not just on investigating the lighting inside toilets but working towards lighting a six metre radius around the toilets so we have street lighting based on pee power.”

Dunster House has designed and manufactured a bigger superstructure with two additional privacy panels. This Emergency Pissoire is based around the Dunster House humanitarian range.

Dunster House Director Chris Murphy said, “As a company that is constantly moving forward and searching for new solutions we are really excited that we can take part in this project. Our mission is to help resolve as many humanitarian issues as possible and we truly believe that our products can make a difference, especially in developing countries.”

UWE Bristol researchers and student ambassadors will be on hand during the festival to help explain how the Pee Power Unit works. There will be other MFC demonstration units next to the urinal, allowing the public to engage with the technology in an interactive manner.

Pee Power is just one of a series of public engagement, research and volunteering opportunities that UWE Bristol is showcasing at Glastonbury 2016.

Glastonbury organisers have said that it is vital that festival goers do not pee on the land as it pollutes the river than runs through the site and harms fish and other wildlife.
